Note:If we specify the precision greater than the precision of the data type itself (7 forfloatand 15 fordouble), then the compiler will give us garbage values after the precision limit has been exceeded, as can be seen with thefloatoutput inexample 2. Work with Exponential Numbers As ment...
上面那个 "_embedding_bag_cpu_impl_out" 就是那把“剑”,我们可以看到出现 Invalid read 的地方是 cpublas_axpy_impl,是从 EmbeddingBag.cpp#L446 这个地方调进去的。另外可以猜出来应该是 src 或者 output 的越界,因为这两个的 data type 是 float。如果是 index 越界,应该是 8 个 bytes (data type int...
